Well I got it to work finally... Here is how:
1. Removed the switch from the prop valve and re-centered the valve. Re-installed the switch.
2.Re-bled the brakes but this time I did the gravity method, starting with the rears on the right side.
3. After the bleed the pumped the brake pedal a few times and let it set. Meanwhile I re-checked the switch with the test light, no light all is good.
4. Re-bled the brakes once more, gravity method once again.
5. Cleaned up and took it for a spin!
